Washington Revised Code Title 7. Special Proceedings and Actions § 7.28.085. Adverse possession--Forestland--Additional requirements--Exceptions

(1) In any action seeking to establish an adverse claimant as the legal owner of a fee or other interest in forestland based on a claim of adverse possession, and in any defense to an action brought by the holder of record title for recovery of title to or possession of a fee or other interest in forestland where such defense is based on a claim of adverse possession, the adverse claimant shall not be deemed to have established open and notorious possession of the forestlands at issue unless, as a minimum requirement, the adverse claimant establishes by clear and convincing evidence that the adverse claimant has made or erected substantial improvements, which improvements have remained entirely or partially on such lands for at least ten years. If the interests of justice so require, the making, erecting, and continuous presence of substantial improvements on the lands at issue, in the absence of additional acts by the adverse claimant, may be found insufficient to establish open and notorious possession.

(2) This section shall not apply to any adverse claimant who establishes by clear and convincing evidence that the adverse claimant occupied the lands at issue and made continuous use thereof for at least ten years in good faith reliance on location stakes or other boundary markers set by a registered land surveyor purporting to establish the boundaries of property to which the adverse claimant has record title.

(3) For purposes of this section:

(4) This section shall not apply to any adverse claimant who, before June 11, 1998, acquired title to the lands in question by adverse possession under the law then in effect.

(5) This section shall not apply to any adverse claimant who seeks to assert a claim or defense of adverse possession in an action against any person who, at the time such action is commenced, owns less than twenty acres of forestland in the state of Washington.
